How to dynamically define a class method which will refer to a local variable outside?

Question

class C
end

var = \"I am a local var outside\"

C.class_eval do
   def self.a_class_method
     puts var 
   end
end

I know, this is not correct, beca

Answer 1

C.instance_eval do
  def class_method
    "This is class method"
  end
end

instance_eval: defines singleton methods on the object (which results in class methods when it's called on class object).

class_eval: defines regular instance methods
